Gamma 2 Delphinus
What is Gamma 2 Delphinus
Gamma-2 Delphini forms, with its brighter companion Gamma-1, one of the finest visual binaries in the summer sky: two pale-gold suns some 126 light-years away, set in the small dolphin like a double droplet at the creature’s muzzle. It is a tempered orange K-type giant, and the pair splits cleanly through any amateur telescope, offering one of the most rewarding views for anyone meeting their first visual double in a calm summer night.
Where it is and when to see it
Gamma 2 Delphinus lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.

The signature wall
Stelvia's sky works like a signature wall: anyone can leave their name and a message on a real star, and that signature goes up on the map for everyone to read. Signing is free.
A signature without a lock can be replaced by someone else's. The lock makes the signature permanent and lets you choose a symbolic name for the star, always shown next to the star's catalogue identifier. How the lock works

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
